Glanville's X-rated response? "Well, Mohamed did tell me that her p--sy smelled," she said. "It's true! I'm not lying! And Lisa Vanderpump was there when he said it. Sorry, bitch. I win!"

From there, the feud escalated even more on social media. Hadid tweeted, "Andy @andy. That a lie. I never spoken to Brandy @BrandiGlanville in any way about joanna. Brandy is She is such a scum and a foul mouth." He also wrote a note to his ex-wife: "@YolandaHFoster. I love you mother of my children and my best friend. U know I don't have a foul mouth and I would never use words to brandi." (Married from 1994 to 2000, Hadid and Yolanda share kids Gigi, Bella and Anwar.)

Foster, 49, who has been married to Grammy-winning musician David Foster for two years now, wrote, "Only @MohamedAHadid @joannakrupa & God know d truth of this 12 yr old accusation, l choose 2focus on d now &spare my babies this negativity."

While Hadid, Foster and Krupa appear to be keeping the peace following the accusations, Glanville seems to be especially remorseful for her comments.

"My morning is ruined," she tweeted the next morning. "Im crying and going back to sleep bye." She later added, "It was not my intention to hurt anyone last night, I spoke my truth when asked a question-fought back when attacked I love @YolandaHFoster."
